Analysis on the Carrier Phase Shift Technology for Harmonic Current Elimination in the High-power Electric Locomotives

大功率电力机车四象限变流器通过载波移相控制技术消除牵引网侧高次谐波。对四象限脉冲整流器的载波移相控制技术进行了理论分析，通过对两重化脉冲整流器网侧谐波含量仿真及对某型电力机车的实测网侧数据的分析，验证了载波移相控制技术在抑制电力机车向网侧注入谐波时的有效性及实用性。

Four-quadrant inverter of high-power electric locomotives eliminates the high-order harmonics of the traction network side by carrier phase shift control technology. In this paper, four-quadrant pulse rectifier carrier phase-shift control technology was theoretical- ly analysed. Base on the analysis of simulation result and data in the test, the effectiveness and practicality of the phase shift control technology for restraining the harmonic was validated.
